Name: MPEG-1 Program Stream
Description: MPEG-1 is a lossy compression standard for video and audio, intended for use in Digital Storage Media (DSM) such as VideoCD and DVD (at the same encoding standard as VCD). It is designed to handle video frame-sizes of 352 x 288px, at a frame-rate of 25 frames per second (PAL) and a data rate of around 1.2Mbits/s; audio: up to 320 kbits/s (MPEG-1 Audio Layer III, .mp3). MPEG-1 supports random access to stream content on playback. MPEG-1 Video supports only 'progressive' frame video. MPEG-1 compression can be relatively inefficient by modern standards. An MPG-1 ‘Program’ stream (PS) file (.mpg, *.mpeg) generally contain both video and audio streams, generally for synchronised playback, and may carry a variety of other data (e.g. video captions).
